The old man works. He dies. He has to pay estate tax. Unless he has bought life insurance, which will cover the estate tax. Who sells that? Warren Buffet. Ok, part B. Old man dies. Has no insurance to pay lovely IRS. Wife, kids whatever are dolts and can't do what the old man did and no one in their right mind is going to loan the dead rich man's kids the money to pay the estate. Guess who specializes in buying unique family run companies from widows and rich kids? Warren Buffet. Nice. The guy is a vulture.
I read somewhere he has made a fortune off other's misery.
